The SpillX System
The SpillX system has been designed to fit with today's existing locomotive and fueling infrastructure. The dry break nozzle attaches to fuel cranes or DTL trucks using the standard 2-1/2" cam lock connection and installation takes less than 5 minutes. Similarly, the locomotive mounted components have been designed so that they can be installed in a matter minutes with no modification to the locomotive tank.
The pressure drop of the SpillX nozzle and receiver is significantly less than the current system, which allows for higher flow rates at the same fueling pressure. The result is increased fueling rates of up to 75% or more by simply changing to SpillX components and maintaining the same pressure at the nozzle.
The SpillX system is capable of accepting higher fueling pressures, typical to those seen in the aviation industry. What this means is that the system is capable of flow rates upwards of 600 GPM, given sufficient nozzle pressure. The system does not introduce air into the system, thus there is no diesel foaming that occurs in the filler neck. Dry-break connections on the nozzle and receiver ensure fueling connection safety while fueling, and keeps the fuel contained in a closed system at disconnect.
In addition to the ability to increase flow rates, the system also offers an internal hydraulic shut off mechanism which serves as the automatic overfill protection. This hydraulic mechanism stops the flow of fuel into the locomotive even when the nozzle is still connected and open. The float determines the proper level has been reached and causes the receiver to begin a gradual shut off of fuel into the tank. This shut off occurs over a period of 4-6 seconds which virtually eliminates the "fluid hammer". The gradual shut off prevents pressure spikes in the line and reduces wear and tear on pumps and infrastructure.
